An eight-page search warrant obtained by KCCI in June explained how he preyed on the teenage girl. It all came to light on June 7 when a family member discovered an SD card containing graphic pictures and videos of Troxel performing sex acts on the victim.

Police later discovered Troxel has been allegedly abusing the girl for three years.

Officers seized a list of evidence from his Ottumwa home including two SD cards, a digital camera, his cell phone, laptop and drug paraphernalia.
